A method and system for providing a magnetic structure in magnetic transducer is described. The method and system include providing a pinning layer, a synthetic antiferromagnetic (SAF) adjacent to the pinning layer, a nonmagnetic layer, and a sensor layer. The SAF resides between the nonmagnetic and pinning layers. The nonmagnetic layer is between the SAF and the sensor layer. The SAF includes a pinned layer, a reference layer, and a nonmagnetic spacer layer between the pinned and reference layers. The pinned layer is magnetically coupled with the reference layer and includes sublayers. A first sublayer has a first blocking temperature distribution (TBD) and a first exchange energy. A second sublayer has a second TBD and a second exchange energy. The first sublayer is between the pinning layer and second sublayer. The first TBD is greater than the second TBD. The first exchange energy is less than the second exchange energy.
